This study identifies a unique sodium permeability in the C. elegans K2P channel UNC-58, driven by an atypical cysteine residue in its selectivity filter, highlighting the need for functional experiments to understand sequence variations in potassium channels.

The paper describes a CRISPR/Cas9 strategy for efficient and scarless genome editing in C. elegans using a single sgRNA and a selectable phenotype, enabling precise deletions, reporters, and fusions.
